Insights
Reviva Pharmaceuticals Holdings, Inc.'s recent announcement regarding the advancement of its schizophrenia treatment, brilaroxazine, presents significant implications. The Positive and Negative Syndrome Scale (PANSS) is a recognized metric for assessing treatment efficacy in schizophrenia and the reported 10.1-point reduction suggests a substantial clinical impact. Furthermore, the drug's drug-drug interaction profile is crucial for patient compliance and safety, as many patients with schizophrenia are on multiple medications.
The registrational Phase 3 RECOVER-2 trial and the New Drug Application (NDA) submission planned for 2025 represent critical steps towards commercialization. The successful completion of these could significantly expand treatment options for schizophrenia, a market that is in need of novel and effective therapies. The potential expansion of brilaroxazine's indications to other neuropsychiatric and inflammatory conditions could further increase its market potential.
The $30.0 million capital raise through a registered direct offering indicates strong investor confidence and provides Reviva with the necessary funds to continue its clinical trials. This financial boost is essential for the company's sustainability and progression towards commercialization. The inclusion in the Russell Microcap® Index may have also contributed to increased visibility and liquidity for Reviva's stock.
In the context of the biopharmaceutical sector, successful Phase 3 trials can lead to significant stock price movements, as they often precede FDA approval and commercialization. Investors will closely monitor the upcoming topline data from the OLE trial and the initiation of the RECOVER-2 trial. Positive results could lead to partnerships or acquisition interest, while any setbacks could have negative repercussions for the company's valuation.
The schizophrenia treatment market is highly competitive, with a need for drugs that offer efficacy without severe side effects. Brilaroxazine's tolerability profile, as indicated by the lower discontinuation rates compared to placebo, positions it favorably against existing treatments. The drug's once-daily dosing could also offer improved patient adherence compared to existing therapies that require more frequent dosing.
Reviva's strategic move to explore brilaroxazine's application in other conditions such as psoriasis and idiopathic pulmonary fibrosis (IPF) could address a broader range of unmet medical needs. The potential for label expansion post-approval could create additional revenue streams and provide a competitive edge in the CNS and inflammatory disease markets.

CUPERTINO, Calif., Jan. 04, 2024 (GLOBE NEWSWIRE) -- Reviva Pharmaceuticals Holdings, Inc. (NASDAQ: RVPH) (“Reviva” or the “Company”), a late-stage pharmaceutical company developing therapies that seek to address unmet medical needs in the areas of central nervous system (CNS), inflammatory and cardiometabolic diseases, today provided program updates and announced upcoming key milestones.
“In 2023, we made significant progress across our late-stage brilaroxazine clinical program in schizophrenia, including positive topline Phase 3 data demonstrating statistically significant reductions across all major symptom domains, successful ongoing enrollment in our one-year OLE trial, and positive clinical drug-drug interaction data supporting a competitive profile for once-daily brilaroxazine,” said Laxminarayan Bhat, Ph.D., Founder, President, and CEO of Reviva. “We also furthered foundational preclinical support for the therapeutic potential of brilaroxazine in other inflammatory conditions driven by underlying serotonin signaling dysfunction, including psoriasis and idiopathic pulmonary fibrosis (IPF). We believe these advances reinforce the broad potential of brilaroxazine to be a safe and effective therapy for major neuropsychiatric and inflammatory indications caused by a dysfunctional serotonin-dopamine system. Importantly, our recent progress brings us closer than ever to fulfilling our mission of reviving the full promise of patients’ lives with treatment paradigm changing drugs targeting neurotransmitter-driven diseases. As we look ahead, we expect 2024 will be a pivotal year for Reviva as we continue the momentum in schizophrenia with topline data from our OLE trial expected in the fourth quarter of 2024 and initiation of a registrational Phase 3 RECOVER-2 trial expected in the first quarter of 2024. Collectively, these data are designed to support our New Drug Application (NDA) submission to the U.S. Food and Drug Administration (FDA), expected in 2025.”
Pipeline Program Updates

About Brilaroxazine
Brilaroxazine is an in-house discovered new chemical entity with potent affinity and selectivity against key serotonin and dopamine receptors implicated in schizophrenia and its comorbid symptoms. Positive topline data from the global Phase 3 RECOVER trial in schizophrenia demonstrated the trial successfully met all primary and secondary endpoints with statistically significant and clinically meaningful reductions across all major symptom domains at week 4 with 50 mg of brilaroxazine vs. placebo with a generally well-tolerated side effect profile comparable to placebo and discontinuation rates lower than placebo. Positive data from a clinical drug-drug interaction (DDI) study investigating the potential effect of CYP3A4 enzyme on brilaroxazine in healthy subjects supports no clinically significant interaction when combined with a CYP3A4 inhibitor. Reviva believes that a full battery of regulatory compliant toxicology and safety pharmacology studies has been completed for brilaroxazine. Reviva intends to develop brilaroxazine for other neuropsychiatric indications including bipolar disorder, major depressive disorder (MDD) and attention-deficit/hyperactivity disorder (ADHD).
Additionally, brilaroxazine has shown promising nonclinical activity for inflammatory diseases psoriasis, pulmonary arterial hypertension (PAH) and idiopathic pulmonary fibrosis (IPF) with mitigation of fibrosis and inflammation in translational animal models. Brilaroxazine has already received Orphan Drug Designation by the U.S. FDA for the treatment of PAH and IPF conditions.
